ODORLESS EXOAVATING A PPARATUS.

SPECIFICATION forming part of Letters Patent No. 373,938, dated November29, 1887,

Application filed June 25, 1887. Serial No. 242,535. (No model.)

.To all whom it may concern.-

Be it known that I, REUBEN A. MOOAULEY, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Odorless Excavating Apparatus; and I dodeclare the following to be a full, clear, and exact description of theinvention, suchas will enable others skilled in the art to which itappertains to make and use the same, reference beinghad to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention relates to apparatus which is employed in the excavationand cleansing of sinks, vaults, and other places where offensivedisseminated-during the process of excavation and it consists inproviding a specially-designed folding tent which may beplaced in suchposition about the vault or sink to be operated upon that the entireapparatus and operationmay be concealed from view; and my inventionfurther consists in providing a specially designed (leodorizer which issuspended inside of the tent, whereby the escapthe offensivegases fromthe sink, willbe caused to mingle as they escape to the atmosphere, andthe offensive gases rendered odorless and structed that it may readilybe placed in position for operation or removed and folded into a smallspace for convenience of transportation.

In the further description of my invention reference is had to theaccompanying drawings, in which- Figure 1 is a front elevation of thetent, partly in section. Fig. 2 is aside elevation in section of thedevice complete. Fig. 3 is a detailed front elevation, partly insection, of the deodorizer. Fig. 4 isa detailed side elevation, partlyin section, of the deodorizer. Fig. 5 is a detailed View of the foldingframe, showing construction of crossbeams.

The same figures refer to the same or similar parts throughout theseveral views.

The figure 6 denotes the folding tent, which in Fig. 2 is representedattached to a privy, 7, in which the excavating or cleaning is to beperformed, the tent 6 forming an inolosure around that part of the privyin which is the door or opening 8. The said tent 6 is constructed with afolding frame, which consists of the uprights 9, to which is hinged, bymeans of an eyebolt, 10, and hook 11, the arm 12. which by this methodof securing may be folded close to the upright 9. The free ends of thesearms 12 are each provided with a crossbeam, 13, which meet and overlapone another, Fig. 5, and are held together by an eyebolt, 14, in suchmanner as to permit a fold of these two cross-beams 13 to be made atthis point, a pin, 15, being provided, which passes through both beams13 when it is desired to hold them in the extended position.

The upper endof the upright 9 is provided with two cross-beams,16, whichmeet and overlap in the same manner as those described on thefree endsof the arms 12, the eyebolt 17 serving as a pivot and to secure the saiderossbeams 16, a pin, 15%, being provided to hold them in the extendedposition, as in the case of those beams on the arm 12. When in positionfor operation,the arm 12 is held extended by means of the rod l8,whichis provided with an eye, 19, at one end thereof, by which it is securedto the eyebolt 14, the other end of the said rod 18 being provided withthe hook 20,

by which it may be readily secured in the eyebolt 17.

The structure is secured in its proper position by resting the uprights9 upon the ground and securing the upper portion thereof by means of arope, 21, which may be made fast to a nail or book, 22, temporarilysecured to some suitable part of. the privy. The entire frame, with theexception of that part which adjoins the privy 7, is covered with acanvas covering, 23,- sufficient space being afforded therein to performall the operations of excavation, the frame and its cover 23 being drawnsufficiently close to the privy 7 to prevent the escape of any gasesexcept through the opening 24 in the cover 23, which is provided forthis purpose.

In order to render the escaping gases odorless and harmless thedeodorizer 25 is provided and suspended from the rod 18 by its bail 26,the said deodorizer 25 consisting of the casing 27, in which is placed alamp, 28,which may be of common construction and has a thumbscrew, 29,for the adjustment of the flame. The chimney is constructed of sheetmetal and has an aperture, 31, therein,whieh is protested withisinglass, in order that the flame 32 may be observed for properadjustment. Supported on the chimney 30,in such manner that the heatfrom the flame 32 will impinge thereon, and at the same time affordsufficient ventilation for the said flame, is the evaporating-pan33,which serves to evaporate the deodorizing-mixture (carbolie acid orany suitable disinfectant) as it is dropped from the reservoir 34,whichis secured to some part of the deodorizer 25 above the evaporating-pan33, and is provided with the cock 35,whereby the quantity ofdisinfecting material supplied to the evaporating-pan 33 may becontrolled,

thegases from the deodorizer, when they are set free, mingling with thegases from the sink in their escape through the opening 24, whereby theoffensive gases will be disinfected and rendered odorless and harmless.

The manner of operating is as follows: In Fig. 2 is represented a cash,3G .wl1ich has an opening provided with a hermetically-sealing cap, inorder that no gases may escape from the cask when being transported. Thetent 6, as represented in Fig. 2, may be made sufficiently large toafford room inside for this cask 36 and the operators to perform thenecessary work, which is done with the bucket 37 by dipping the soilfrom the sink and pouring into the cash 36. The deodorizing apparatushaving been put in operation by lighting the lamp 28 and adjusting thecock 35 so that sufficient of the disinfecting material may be caused todrop upon the evaporating-pan 33 and be evaporated in the mannerheretofore described, these disinfecting gases from the evaporatingpan33 pass through the opening 24c and sufficiently mix with the gases fromthe sink to disinfect the latter and render them odorless. Vhen the cask36 is filled, its hermetically-sealed cap is placed thereon, 'when thecask may be removed, anothersubstituted, and the operation continueduntil the work is completed.

I do not, however, confine myself to the use of the cash 36 in the tent6 and the employment of the dipper or bucket 37 for dipping the soil, asthe tent and deodorizer may be employed with equal advantage when apumpis used and the soil raised by suction and forced into the cask 36 or atank, as is now commonly done. In this latter operation, though adeodorizer is placed over the vent of the transporting-vessel, a greatevil still exists in the offensive gases which arise from the sink,caused by and during the process of pumping. By placing the tent 6around the door 8 of privy 7, with the deodorizer 25 therein, thisdefect will be remedied and the offensive gases from this source berendered odorless and harmless, in the manncrhcrctofore described.

There may be occasions when it would not be practicable to employ thetent (l, in which case a pump can be used for excavating, as in commonuse, and the opening 8 in the privy 7 closed, a vent being formed insome convenientpart of the privy. and the dcodorizcr 25, hereindescribed, is placed within the privy 7, whereby the escaping gases fromthis source will deodorize in the manner described.

Having described my invention and the manner of operating, what I claim,and desire to secure by United States Letters Patent, is

In an odorless excavating apparatus, the combination of a tent orscreen, 23, provided with an opening, 24, at its top, and adeodorizing'stove, 25, consisting of the casing 27, the bail 26, thelamp 28, the evaporating-pan 33, the chimney 30, and a reservoir, 34,provided with the cook 35, the said deodorizing-stovc 25 being suspendedwithin the said tent 23, whereby a current of air is created through thesaid opening 24 by the heat from the said deodorizing-stove and theheated disinfecting-gases arising therefrom, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
